Title: Improvements in and relating to methods for joining electrical connections to thermoelectric materials
Inventor: WILSON GEOFFREY WILFRED
IPC: H01L35/08
Filed: 1964-09-21
Abstract: 1,120,552. Brazing. INTERNATIONAL RESEARCH & DEVELOPMENT CO. Ltd. 25 Aug., 1965 [21 Sept., 1964] No. 38457/64. Heading B3R. [Also in Division H1] A metallic member is joined to a thermoelectric element comprising germanium telluride or germanium bismuth telluride by coating the metallic member with a layer of eutectic nickel phosphorous alloy. The process further comprises abrading the layer of NiP alloy to give a clean smooth surface, pressing the alloy into intimate contact with the element and heating in an inert atmosphere to below the alloy melting point but sufficient to ensure diffusion of the NiP alloy to produce a bond. The bonded member and element are preferably cooled slowly. A stainless iron or mild steel connecting member is coated with NiP eutectic alloy and heating to 880 C. to braze the alloy to the member. After cleaning, the member is held against a P-type pellet of the thermoelectric material using a spring clamp and the assembly heated in argon at 600-650 C. for 5-30 minutes. The thermoelectric elements may be joined to lead telluride or lead-tin telluride elements of the type described in Specification 1,120,551.

Abstract: 1431579 Locks KEYSTONE INDUSTRIES Inc 14 Aug 1973 [28 Aug 1972] 39515/73 Heading E2A [Also in Division F2] The slamming force of a vehicle door is damped by a hydraulic dash-pot piston 45 as it strikes the door frame [see Division F2], and the door is then firmly closed by a pivoted latch bolt 106 engaging a striker 148 and forced into its fastening position by an electromagnet 82 which is energised in a door position in which the latch bolt has been turned, by engagement of the striker, to its safety latching position. The energisation of the electromagnet is effected by a N.O. limit switch 156 on the door and is cut off when the door is fully closed by a N.C. switch 157. The bolt 106 is pivoted at 108 and is held at abutments 109, 110 by a pawl 112 which may be released, in the usual way, through linkworks by inside and outside handles. The bolt has a projection 116 which may be engaged by a hook 132 on a link 130, Fig. 12, lifted by a clevis 92 on a lever 87, Fig. 2, tilted by the electromagnet 82. Partial rotation of the bolt engages the hook, and thereafter, upward movement of the hook, draws the bolt to its fully fastened position, after which, de-energisation of the electromagnet allows the hook to drop to a position which allows manual release of the holding pawl. This manual action activates a cut-out switch which prevents energisation of the electromagnet as the door is being opened. The electromagnet may be replaced by a pneumatic or hydraulic cylinder. The damper or lock may be on the frame instead of the door.

Abstract: 1427728 Automatic exchange systems PLESSEY CO Ltd 9 Aug 1973 [25 Aug 1972] 39668/72 Heading H4K An exchange system is arranged as a plurality of control areas each including a common control centre exercising control via data links upon a plurality of remote switching units and each control area is divided geographically into a plurality of sectors each including a plurality of remote switching units so that if the common control centre for the control area should fail, the control responsibility for each sector can be transferred to a geographically adjacent control centre. The Figure shows within a rectangle the control area for common control centre CCU1 which area is sub-divided into four sectors SUB-AREA 1 to 4. In addition to the data links, e.g. DLX, DLA, DLN connecting the remote switching units with their area control centre there are provided standby data links, e.g. SBDLA linking each sector with a respective geographically adjacent control area. The control centres CCU utilize stored programme control and have stored in a backing store the interconnection pattern and a recent directory to equipment number translation table for those sectors which they may have to take over. Failure of a control centre, e.g. CCU1 is detected by data path monitors associated with the remote switching units and the detection results in the enabling of the standby data path(s) for the sector(s) and the receipt of an alarm signal at the standby control contre(s). On receipt of this alarm a standby control centre signals a maintenance control centre MCC and the receipt of such signals from four standby control centres indicates total failure of control centre CCU1. Each standby control centre rearranges its operation to include the extra sector and the information in its backing store concerning the sector is updated by information supplied by the maintenance control centre. The changeover is capable of being achieved in about 20 secs. To overcome the problem that the standby control centre has no knowledge of the existing calls in the sector taken over all existing calls may be forced released after a period of time, e.g. 5 mins. A marker arrangement capable of performing this operation is disclosed in Specification 1,383,107.

Abstract: 1,219,947. Oxidation of hydrocarbons. HALCON INTERNATIONAL Inc. 22 Aug., 1968 [24 Aug., 1967], No. 40236/68. Heading C2C. A process for the production of alcohols and/or ketones comprises oxidizing a hydrocarbon in the liquid phase with molecular oxygen in the presence of a boron adjuvant, the water partial pressure in the gases in contact with the reaction mixture being reduced during the course of the reaction. The process is applicable both to batch and continuous type oxidation systems. The water partial pressure can be reduced by varying the oxygen content of the oxidant gas stream e.g. by varying the amount of inert gases in the gas stream or by varying the amount of hydrocarbon boil-up e.g. by heat input and/or by regulating the temperature and pressure. Examples oxidize cyclohexane and dodecane in the presence of meta-boric acid.
